Question

In ecotone which species become abundant?

• A. Sibling species
• B. Endemic species
• C. Rare species
• D. Edge species

Answer 1

The correct option is D Edge species

Ecotone is the transition zone between two communities e.g., forest and grassland.

Ecotone has a mixture of species belonging to both the communities. Ecotone possesses higher number of species than either of two communities.

The increased number and even density of species in the region of ecotone or community border is called as the edge effect.

The species, which are found primarily or most abundantly or spend most of their time in ecotone are known as edge species.

So, the correct answer is 'Edge species'
